I used the same criteria that is used to put an issue in a queue for alerting people when it is created. I set the alert to go to JIRA users that were not associated with the Service Desk project but they never got emails. Even after adding the people as agents to Service Desk, they never received emails. If I add myself to the alert user action I get an email. Do people added to an alert user action need to have a specific role within a Service Desk project in order for the alert to get sent to them?
